What's the manga used for peccatore sanctuary's "sinfully shocking" recruitment image? It looks to be the same art as Junjou romantica but I can't seem to place it. Please and thanks

guessing this is the one you're talking about: This one
if it is, you were right and it is by Nakamura Shungiku. It's probably for a novel
